Physics- Kinematics

what are the four fundamental forces of nature?

gravitational force, electromagnetic force, weak nuclear force, and strong nuclear force

describe the gravitational force

a force of attraction between masses, weakest force in nature, acts over large distances and near the surface of the earth, causes all masses to accelerate downwards at 9.80m/s

describe the electromagnetic force

a force of attraction between charged particles, stronger than gravity, binds electrons to the nucleus of atoms, and everyday pushing and pulling are examples of this force

describe the strong & weak nuclear forces

acts over short distances- within the nuclei of the atom, strongest force in nature, and responsible for holding nucleus together, and for nuclear energy

what is newtons 1st law>

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it

What is Newton’s second law?

acceleration is directionally proportional to the net force applied and inversely proportional to the mass of the body

What is Newtons third law?

to every action, there is an equal and opposite reaction.
